backup alternator

backup alternator

I own a 1981 C172RG. As I fly very frequently in rather hard IFR weather (IFR weather is usual in this part of Europe) I would like to add a second alternator (and battery) in case the main one gives it up (I had already an emergency because of alternator failure, in hard IFR and at night, in 1996, and this week I was reminded to it because of an alternator malfunction).For the 172RG the problem is that there isn't any output left on the engine accessory case. Thus the only remaining solution would be a second alternator (on the left side, next to the starter), with a second belt - in that case the flywheel has te be changed, i.e. with two pulleys instead of one). In fact, I have been told that this is also used on the 210.Does anyone knows of such (or any else workable) solution on the market for a Lycoming O-360 ?

Re: backup alternator

Hi Jan . . .

Your situation is an all too common one with single engine IFR aircraft. Most engine accessory cases are already packed solid and the addition of another sheave (pulley) simply gives you another belt that requires inspection and is subject to failure.

Another option is a Turbo Alternator Power Backup System. In simple terms this is a completely self-contained wind driven alternator that can be attached to a swing-out bracket and located in the airframe. Possible locations - for your aircraft - might include the cowl or the baggage compartment door.

One manufacturer, of such equipment, is Basic Aircraft Products, Inc. of Evans, Georgia - USA. Their web site address is: www.basicaircraft.com and I have been considering one of these systems for exactly the same reasons you set forth. Additionally, if this system is isolated electrically it becomes a totally redundant power source that could prevent quite a few emergency situations. I hope that this helps - good luck, and . . .

And also kindly provide the condition and price of the Goods.Waiting to hear from you very soon.Thanks,Earl M. White wrote:
